Beschreibung
Zusammenfassung:	A friction stir welding apparatus (10A) is used at a butted portion (33) where a second workpiece (32) is butted against a first workpiece (31) such that the second workpiece (32) is upright on the first workpiece (31). The friction stir welding apparatus (10A) includes: a rotary tool (11) that is plunged into one inner corner (33a) of a pair of inner corners (33a, 33b) that are positioned, at the butted portion, on both sides of the second workpiece (32), respectively; an inner corner presser (20) that presses the other inner corner (33b) of the pair of inner corners (33a, 33b); and a mover (15) that moves the rotary tool (11) and the inner corner presser (20) along a direction in which the butted portion (33) extends. The inner corner presser (20) includes a pressing roller (21) that presses the other inner corner (33b) while rolling in a state where the inner corner presser (20) is being moved by the mover (15).
